WPLG meteorology Brandon Orr found plenty of "cold stunned" iguanas across Miami and Fort Lauderdale.
At Miami International Airport, temps dipped to 41 degrees - the lowest mark since December 28, 2010.
Freeze warnings remain in effect in Florida until 8:00 a.m. EST this morning-9:00 a.m. for other parts of the state-according to NWS.
On Wednesday, the National Weather Service confirmed that their forecast was correct, retweeting a photo of a fallen iguana shared by National Hurricane Center scientist Eric Blake.
This isn't a new phenomenon for many Florida residents. In general, iguanas begin to get sluggish or lethargic once the temperature drops below 50 degrees Fahrenheit.
"Iguanas are cold blooded".
Iguanas weren't the only thing to shut down in Florida due to the weather this week. However, as communications director Ron Magill for the Miami Zoo told CNN it is the body's way of protecting the iguanas till temperatures are warmer.
If the temperatures remain in the 40s for a period of over eight hours, many iguanas could die, especially hatchlings, according to The Bismarck Tribune.
Iguanas aren't unsafe or aggressive to humans, but they damage seawalls, sidewalks, landscape foliage and can dig lengthy tunnels. They've been in South Florida since the 1960s, but their numbers have increased dramatically in recent years.
